How do you reset check engine light for the 2009 Chevy trail blazer?
There is not one sensor. All the ECM sensors are tied to the check engine light.
Have vehicle scanned to determine the problem with the emission system
You can either bring it in to a Chevy dealer or use a programmer/tuner to reset the check engine light.
If the check engine light is blinking that means an engine cylinder misfire has been detected
Check
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle.
It requires an engine scanner to do that.
No, only a problem that effects emissions will set the check engine light.
When the check gauge light comes on in the 1995 Chevy Cheyenne, it means there is a problem with the transmission. If the truck won't shift in to overdrive, there is most likely a problem with the VSS system. The transmission needs to be removed so the VSS can be accessed.
A flashing check engine light is an indication of a misfire.
That REQUIRES an ENGINE SCANNER to do that.
